摘　　要：为了探讨生态治理对大渡河干旱河谷区域植被群落碳汇能力的影响,选择该区域经生态治理形成的侧柏林(POF)、岷江柏林(CCF)、云南松林(PYF)、刺槐林(RPF)、仙人掌灌丛(ODS)等植被群落和自然发育形成的灌丛群落(UDS)为研究对象,探讨其不同植被层和土壤层的碳储量(t/ha)分配特征.研究发现,CCF的碳储量较高(171.48 t/ha),其次,POF(149.69)>RPF(138.74)>PYF(76.54)>ODS(76.45)>UDS(65.70)t/ha.CCF碳储量(t/ha)在土壤层(129.7)、植被层地上部分(33.83)和凋落物层(3.10)的值均高于其他植被群落.表明生态治理显著增加了大渡河干旱河谷区域主要植被群落的碳储量,其中,营造岷江柏林模式下形成的植被群落碳汇潜力较大.This study aims to examine the carbon sequestration capacity of vegetation communities under eco-logical management in the arid valleys of the Dadu River.The distribution of carbon storage in different vegetation layers and soil layers in the vegetation communities under ecological management were compared,including Platy-cladus orientalis forest(POF),Cupressus chengiana forest(CCF),Pinus yunnanensis forest(PYF),Robinia pseudo-acacia forest(RPF)and Opuntia dilleniid shrub(ODS),as well as an undisturbed shrub community(UDS)serving as the control.The results showed that the total carbon storage of CCF(171.48 t/ha)was higher,and POF(149.69)>RPF(138.74)>PYF(76.54)>ODS(76.45)>UDS(65.70)t/ha.In the CCF,the carbon storage of soil layer(129.7 t/ha),the above-ground of vegetation layer(33.83 t/ha)and the litter layer(3.10 t/ha)were higher than those in the other vegetation communities.We conclude that ecological management significantly increases the carbon storage of the main vegetation communities in the arid valley area of the Dadu River,and CCF has a greater potential for carbon sequestration.
